It has been claimed in the literature that selective ethanol separation from ethanol-water solution can be made through ultrasonic atomization. The causes of separation were explained in terms of parametric decay instability of capillary waves, accumulating acoustic energy in a highly localized surface of the capillary wave and effecting ultrasonic atomization. In this study, the atomization process is examined visually with some mechanistic view, and the dynamics of interfacial oscillations occurring along the perturbed protrusion or conical “liquid column/fountain jet” over the ultrasonic transducer are analyzed by high-speed imaging. It is found that the atomization process could be initiated by a sudden increase in surface roughness of microscale, which would be viewed as localized surface patches of two-dimensional capillary waves, often associated with contraction expansion sequence of surface to-pology. Such surface patches could bring further instability in generating a swarm of liquid droplets of microscale around the expanded phase of liquid column.<br>

When mist particles are generated from ethanol-water mixtures by ultrasonic atomization at a low temperature, ethanol is concentrated in the atomized mist particles. This paper explains the mechanisms of ethanol thickning in atomized droplets based on the cluster-level structures analysed by the mass spectrometry. When ultrasonic atomization of equimolar ethanol-water mixture is carried out at a lower temperature, e.g. 10°C, small clusters composed of only ethanol molecules can transfer from the liquid phase to the gas phase, while the large clusters consisting of both ethanol and water molecules cannot move across the interface. This leads to the thickning of ethanol in the atomized mist particles. The cluster-level structures of ethanol-water mixture, which varies with the ethanol concentration and the liquid temperature, directly determines the characteristics of ultrasonic atomization of ethanol aqueous solution.<br>
